From their website - " The Lupinenstraße red light district is around the corner from the Rhein Neckar Gästehaus."
And this is a selling point?? All those red lights must make lead to loads of trafic jams. ( I has going to say "make it hard to leave", but then saw how that would read!!!!)
Even allowing for the location, for an extra €6 I would rather stay here than a Formula 1.
